It makes much more sense if he realized he could now no longer have to worry about Lahabrea or Elidibus shepherding him into a new body on The Source, and allowing him to take part in their plans. Rather, he could fulfill his own ambitions, which is what he is excited to start doing. He detests Lahabera's presence, because he has to kowtow somewhat, since he's only capable of being on The Source until the seal of the Blessing break by Lahabrea or Elidibus's auspices.
Then by this definition, they could have easily done this during times when a person with the Blessing did not exist, i.e. any time before ARR, because the WoL is literally the only person to have a fully powered Blessing.

As for his new body being his spirit form, sure but it was something Ascians were said to be unable to do without Crystals of Darkness, manifest a body of any kind.
I am certain the crystal of darkness was stated to be to how they possess people, rather than manifest a body of any kind.

As for the Harry Potter reference, I don't think that's what was going on here at all.
And in the end, this is what it comes down to, a matter of interpretation, because nowhere else in the story does it imply that the Blessing prevented the other Ascians from journeying to the Source. Nowhere is it stated that the Ascians relied on Lahabrea and Elidibus on providing them hosts to be funneled into to exist on the Source. We can only hope that the other languages carry a more clear meaning, or that this was answered somewhere else.
